The ABB KNX Tenton SBR/U Control Element Series combines a freely configurable push-button interface with an integrated Constant Room Temperature Controller (RTC) for ABB i-bus® KNX HVAC projects. Available as 6-fold (SBR/U6) and 10-fold (SBR/U10) variants in Studio White or Matt Black, each device includes an integrated KNX bus coupler, temperature sensor, and labelling field.

The SBR/U excels as a Class 1 temperature controller (1.0% contribution to space heating energy efficiency) for 2-pipe and 4-pipe fan-coil systems and conventional heating/cooling. Beyond HVAC, rockers handle switching, dimming, blind control, value sending, and scene recall — with the Tenton innovative colour concept (orange = RTC, yellow = lighting, blue = blind, magenta = scene) for clear visual feedback.

Key Features — RTC and Room Control

Room Temperature Control

• Constant room temperature controller for fan-coil (2/4-pipe) and conventional heating/cooling actuators.
• Master / Slave configuration for coordinated control across multiple rooms or zones.
• Fan stage switching: Manual or automatic mode; base-load operation supported.
• Class 1 controller: 1.0% contribution to space heating energy efficiency per ABB classification.
• Integrated temperature sensor — no separate room sensor required for basic RTC operation.

Push-Button Interface

• 6-fold and 10-fold layouts: Freely configurable multifunction control elements.
• Core KNX functions: Switching, dimming, blind/shutter, value sending, and scene recall alongside RTC.
• Status LEDs: Multi-colour feedback per button via the innovative colour concept or standard red/green.
• Mounting: Flush mounted or surface mounted installation.

Applications and KNX Integration

• Hotel guest rooms: Combined RTC and lighting/blind control from one Tenton plate.
• Office fan-coil zones: 2-pipe or 4-pipe RTC with scene recall on adjacent buttons.
• Residential HVAC: Class 1 efficiency-rated controller with integrated sensor for simplified wiring.
• ETS configuration: Import the official .knxprod application (Downloads), configure RTC parameters, Master/Slave groups, and LED colour assignments.
